PROTLA41
Schematics
- Three well-filtered antenna inputs covering the VHF and UHF bands, plus separate
auxiliary UHF input for local channels, CCTV, etc.
- Separate gain control on each input; 4 dB upward slope equalisation on UHF ANT input.
- Line power for a proMHD11L or proMHD11M preamplifier available at UHF aerial input.
- Accurate —30 dB directional monitor point.
- Low mains power consumption for cool and economical running.
- With equipotential bonding point.
